S 15i is a compact, high-performance passive installation subwoofer, designed to accompany our VENU series in a wide range of venues requiring high SPL in a discreet, compact package.

S 15i houses a long excursion 15″ neodymium driver in a bass-reflex and T-lined design and has the versatility to be deployed stand-alone, stacked or flown to fit the needs of the installation.

S 15i can be quickly deployed in any configuration, including cardioid and end-fire, when used with AUDIOFOCUS A Series amplifiers. Armonia presets are also available for Powersoft amplifiers.

S 15i is built with pride in Belgium and coated in tough, weather-resistant polyurea to safeguard your investment. The cabinet front is protected by a rigid metal grill, backed by acoustically transparent foam.
